What are you doing tonight?

The same forecast, weighted for the target. Planetary work barely cares about moonlight; long exposures die on high cloud a visual observer would never notice.

SET UP 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 57

Darkness and moonlight dominate. Faint fuzzies need a genuinely dark sky more than they need steady air.

22000204
CLOUD RETURNS 05:30
SET UP 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 73

Seeing is everything and moonlight is irrelevant. Bright targets punch through twilight, so darkness barely counts.

22000204
CLOUD RETURNS 05:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 52

Tolerates soft seeing, but high cloud wrecks a wide frame and moonlight raises the background everywhere.

22000204
CLOUD RETURNS 05:30
SET UP 22:00 · OBSERVE 22:30–02:30 · 4H · MEAN 44

Needs conditions to hold still for hours. Sustained transparency matters more than any single good hour.

22000204
SET UP 22:00 · OBSERVE 22:30–05:30 · 7H · MEAN 60

Naked eye, whole sky. Total cloud and moonlight are the only things that count.
